This research follows the line of investigation opened some years ago about the generalizability studies and variance components applied to soccer. In this investigation, various matches played during the final phase of the last three World Championships (France'98, Korea and Japan'02 and Germany'06) were observed and coded while their interaction contexts were registered. In total, 58 matches were used for this investigation. The following facets were considered: 5 field areas where the 48 contexts are moved or transformed and 7 different types of match result. The results confirm the linear model, which can be generalized to the universe. The resulting 1% of the variance explained by the World Championship facet (1 point when analyzed singly and 14 points when it interacts with the other facets) allows us to confirm that soccer has not changed over the last three World Championships.  相似文献

This research examines whether Psychology students, when they test clinical hypotheses, follow either confirmatory or disconfirmatory reasoning strategies. Two hundred and six psychology students, divided in four groups, participated. One group received information about the probability that the hypothesis was correct by means of verbal labels, and another group, by means of numerical expressions. An additional group received the information that getting a precise diagnosis was clinically important. In a last group, diagnostic tests allowed them to increase certainty about the hypothesis. Results show a partial use of confirmatory strategies because, although participants did not seek confirming information, they indeed avoided collecting disconfirming information. When the information increased certainty about the hypothesis, confirmatory strategies became more likely. Neither the increase in the task importance nor the numerical expression of the likelihood that the hypothesis was correct seemed to affect the testing strategy used.  相似文献

Building on previous research examining the implications for self-regulation and decision making of construing action at varying levels of abstraction, the authors proposed that construing action in terms of its abstract purposes facilitates orienting one’s decisions toward the standards, characteristics, and goals that define one’s desired self-concept. Consistent with this proposal, desiring for oneself a political candidate’s personal qualities predicted evaluating favorably (in Study 1) and voting for (in Study 2) that candidate to a greater extent among participants focused on the distal future (and presumably construing action at a relatively high-level of abstraction) than the proximal future (and presumably construing action at a relatively low-level of abstraction). Moreover, individuals chronically construing action in high-level terms responded more favorably to advertisements appealing to their desired self-concept (in Study 3) than to product quality. These findings’ implications for decision making are discussed.  相似文献

The purpose of this study was to use cluster analysis to identify differences in goal orientation and motivational climate profiles among students in physical education classes as well as differences among the observed clusters on perceived flow experiences. 983 students of 14- to 15-yr.-olds (M = 14.8 yr., SD = 0.91) from a large Spanish metropolitan school district were participants and completed questionnaires assessing goal orientations, motivational climates, and perceived flow. Analysis showed three distinct clusters with 40.3% of the sample with a High Motivation cluster, 27.6% in a Low Motivation cluster, and 32.2% in a Mastery Motivation cluster. These three clusters differed significantly in ratings of perceived flow. Clusters also showed different composition by sex. Implications of these results with regard to instruction in physical education classes are discussed.  相似文献

This article provides the first demonstration of a reliable second-order conditioning (SOC) effect in human causal learning tasks. It demonstrates the human ability to infer relationships between a cause and an effect that were never paired together during training. Experiments 1a and 1b showed a clear and reliable SOC effect, while Experiments 2a and 2b demonstrated that first-order extinction did not affect SOC. These results were similar to those found in animal and human conditioning and suggested that a similar associative mechanism could explain these effects. However, they can also be used to look into the underlying causal mental model people build and store while they are learning this task. From a cognitive view, overall results suggest that an independent rather than a chain causal mental model is stored after second-order learning in human causal tasks.  相似文献

MV-Algebras and Quantum Computation   总被引:2,自引:1,他引:1  
We introduce a generalization of MV algebras motivated by the investigations into the structure of quantum logical gates. After laying down the foundations of the structure theory for such quasi-MV algebras, we show that every quasi-MV algebra is embeddable into the direct product of an MV algebra and a “flat” quasi-MV algebra, and prove a completeness result w.r.t. a standard quasi-MV algebra over the complex numbers.

The authors proposed a model of depressive symptoms in early marriage in which relationship confidence, defined as perceived couple-level efficacy to manage conflicts and maintain a healthy relationship, mediates the effect of negative marital interactions on depressive symptoms. The model was tested in a sample of 139 couples assessed prior to marriage and 1 year later. As predicted, relationship confidence demonstrated simple negative associations with negative marital interaction and depressive symptoms for all participants. Longitudinal path analyses supported the mediational model for women only. In women but not men, negative marital interaction indirectly had an impact on depressive symptoms through the mediator of relationship confidence. Findings suggest that relationship confidence may be important to understanding links between marital distress and depressive symptoms, especially in women.  相似文献

The reminiscence bump is the effect that people recall more personal events from early adulthood than from childhood or adulthood. The bump has been examined extensively. However, the question of whether the bump is caused by differential encoding or re-sampling is still unanswered. To examine this issue, participants were asked to name their three favourite books, movies, and records. Furthermore,they were asked when they first encountered them. We compared the temporal distributions and found that they all showed recency effects and reminiscence bumps. The distribution of favourite books had the largest recency effect and the distribution of favourite records had the largest reminiscence bump. We can explain these results by the difference in rehearsal. Books are read two or three times, movies are watched more frequently, whereas records are listened to numerous times. The results suggest that differential encoding initially causes the reminiscence bump and that re-sampling increases the bump further.  相似文献

Interaction design of mobile systems is a complex activity because it requires considering new usability and user experience aspects in order to exploit the peculiar characteristics of mobile devices, such as their pervasive and ubiquitous nature. This paper discusses issues about designing, developing and evaluating mobile systems. Italy has a rich cultural heritage, and the focus in this study is on the design of systems that enable interactive exploration of historical sites, not only for enhancing the user experience but also for learning purposes. The experience of the researchers at the Interaction, Visualisation and Usability lab, University of Bari, Italy, in designing a mobile learning system, called Explore!, which supports young students learning ancient history during a visit to archaeological parks, is reported. The evaluation of Explore! through systematic field studies shows that the adopted approach is able to transform the visit to archaeological parks into a more complete and culturally rich experience.  相似文献
